Overview
Alignerr is an American expert marketplace operated by the data platform company Labelbox that pays specialists to train and evaluate frontier artificial intelligence models. Contributors work remotely on tasks such as writing reference answers, ranking model outputs, reviewing code, checking mathematical proofs and probing systems for failure, across dozens of languages and professional domains. The platform screens applicants for genuine subject expertise before assigning work, and supplies the resulting reinforcement learning and evaluation data to laboratories building large language models.
